附件上传遇到的异常

java.lang.NoClassDefFoundError: org/apache/commons/io/IOUtils] with root cause

q缺少io的Jar包，导入commons-io-XX.jar

Expected MultipartHttpServletRequest: is a MultipartResolver configured?

导入commons-fileupload-*.jar

在spring-mvc配置文件中添加:

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">      <property name="maxUploadSize" value="10485760" />  </bean>
